Like most international conflicts, last week's internet war began over a relatively modest squabble, escalating in days into a global fight.
Before WikiLeaks, Operation Payback's initial target was America's recording industry, chosen for its prosecutions of music file downloaders. From those humble origins, Payback's anti-censorship, anti-copyright, freedom of speech manifesto would go viral, last week pitting an amorphous army of online hackers against the US government and some of the biggest corporations in the world.
Charles Dodd, a consultant to US government agencies on internet security, said: "[The hackers] attack from the shadows and they have no fear of retaliation. There are no rules of engagement in this kind of emerging warfare."
The battle now centres on Washington's fierce attempts to close down WikiLeaks and shut off the supply of confidential US government cables. By Thursday, the hacktivists were routinely attacking those who had targeted WikiLeaks, among them icons of the corporate world, credit card firms and some of the largest online companies. It seemed to be the first sustained clash between the established order and the organic, grassroots culture of the net.
But the clash has cast the spotlight wider, on the net's power to act as a thorn not only in the side of authoritarian regimes but western democracies, on our right to information and the responsibility of holding secrets. It has also asked profound questions over the role of the net itself. One blogger dubbed it the "first world information war".
At the heart of the conflict is the WikiLeaks founder, the enigmatic figure of Julian Assange – lionised by some as the Ned Kelly of the digital age for his continued defiance of a superpower, condemned by his US detractors as a threat to national security.
Calls for Assange to be extradited to the US to face charges of espionage will return this week. The counteroffensive by Operation Payback is likely to escalate.
The targets include the world's biggest online retailer, Amazon – already assaulted once for its decision to stop hosting WikiLeaks-related material – Washington, Scotland Yard and the websites of senior US politicians. There is talk of infecting Facebook, which last week removed a page used by pro-WikiLeaks hackers, with a virus that spreads from profile to profile causing it to crash. No one seems certain where the febrile cyber conflict will lead, only that it has just begun.
